What to Do About Calcium Deficiency in Vegetables? Latest Control Methods Explained
Vegetables are an indispensable dish in our daily lives. Eating vegetables can supplement various nutrients for the human body and is very beneficial to human health. There are many varieties of vegetables in our country, and the vegetable planting area in our country is also very large. And vegetables have relatively large nutritional needs during growth. Especially the calcium element, so when we grow vegetables, what should we do if there is a calcium deficiency? Let's take a look together below!
1. Selection of calcium fertilizer
In the process of growing vegetables, if it is found that the vegetables show signs of fertilizer deficiency, then calcium fertilizer must be supplemented in time. The choice of calcium fertilizer is very important. At present, the commonly used type is mainly chelated calcium fertilizer. Chelated calcium fertilizer can be effectively transmitted to the phloem of vegetables, improving the amount of calcium absorbed by vegetables. In addition, we can also choose some mineral calcium. Mineral calcium is not easily fixed, which is beneficial to the absorption of vegetables. At the same time, it will not be affected by factors such as soil and weather. It also contains some other trace elements, which is very beneficial to the absorption of calcium.
2. Application period
When applying calcium fertilizer, we should pay attention to controlling the application period well. The first time should be carried out during the seedling stage of vegetables, because for most vegetables after planting, this is an important period for root development. Properly supplementing some calcium fertilizer at this time can enhance the growth capacity of vegetable roots and promote flower bud differentiation, etc. Then calcium fertilizer should be applied again during the flowering and fruiting stage, because this period is the peak period of nutritional demand for many vegetables. For the common nitrogen, phosphorus, and potassium elements, the absorption speed is relatively fast, and there is basically no shortage. However, calcium fertilizer is relatively difficult to supplement, so we must pay attention to doing a good job of calcium fertilizer supplementation during the flowering and fruiting stage.
3. Application site
When applying calcium fertilizer, we should pay attention to understanding which parts of vegetables are prone to calcium deficiency and supplement accordingly. Under normal circumstances, the young and tender parts of vegetables are relatively prone to calcium deficiency. Moreover, the calcium element in vegetables basically does not move. Therefore, when we spray foliar fertilizer to supplement calcium, we should focus on the young and tender parts of vegetables. If there are fruits, then we should also pay attention to spraying the young fruits. Usually once about a week, spray about three times. Moreover, when spraying foliar calcium, some potassium, boron, and other elements can also be appropriately supplemented, which can mutually promote absorption.
4. Soil environment
The soil environment has a great relationship with the absorption of calcium elements by vegetables. When vegetable roots absorb calcium elements, they generally absorb it in combination with water. Therefore, when applying calcium fertilizer, we should pay attention to maintaining good soil moisture content. Generally, the suitable soil moisture content for many vegetables is around 75%. In addition, we should focus on controlling the nutrient ratio well, and must never apply excessive nitrogen fertilizer, phosphorus fertilizer, etc., and also control the amount of fertilizer applied. Avoid excessive soil salt concentration, which would hinder the absorption of calcium elements by the roots.
The above is a brief introduction to what to do about calcium deficiency in vegetables. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
